To all whom it may concern: i

Be it known that I, ROY O. H YNTER, a citizen of the United States, residing at Venus, in the county of Knox and State of Nebraska, have invented a new and useful Cultivator-Fender, of which the following is a specification.

I The present invention relates to certain. new and useful lmprovements 1n plow and cultivator fenders such as are utilized as shlelds or guards for plants during cultivat1on to prevent the same from belng covered up by the earth loosened'by the plow orcultivator shares, one object ofthe invention being to provide a. device of the character described whichembodies novel features of construction whereby theloose earth is prevented from covering the plant from the top by fallingover the top edges of the fenders now commonly in use. as well as completely protecting the plant from the sides.

Further objects of the invention are to removed from the cultivator. I M p Wlth these and other ob]ects in view, the invention consists 1n certain novel. comblnations and arrangements of the parts as will 0 more fully appear as the descriptionpro- .ceeds; the novel features thereof being pointed out in the appended claims.

: For a full understanding of the invention. reference is to'behad to the following 5 description and accompanying drawin 11 which- Figure *1 is a side elevation of a cultivator,

ing the fender 'to the cultivator.

I Patented I view of one oflthe yielding bars for connect- I:

Corresponding" and like parts are referred to in thefollowing description and indi-' cated in allthe viewsof the Specifically describing the present bodiment of" the invention thenumeral -1 des gnates opposed side plates/which are vertically. arranged and are adapted to travel upon the surface of the ground upon oppoplants to be cultivated, as

clearly shown by Fig. 8, the plant being "shownrby; dotted lines. The front, lower edges of these side plates are beveled .at 1 a v to allow theside plates to easily travel over the ground without v sticking into or; catching upon the same so asto hinder the movevment of the side plates thereover. ;'Super posed upon the upper longitudinal edges of drawings by j the same reference characters.

these side plates 1 are a pair of top plates 2 which converge inwardlyt'oward each other soas to form a substantially inverted V- shaped canopy. These plates 1 and, 2 are hingedly connected to each; other :by a pair of hinge members 3, the said hinge members being formed of fourhingedly connected parts, oneof which is rigidly connected to each of the plates 1 and2 ,of the fender.

These hinge members are clearly illustrated by Fig.-- 4 and are secured to theplates of the fender near the opposite ends thereof by any. suitable means such astherivets 9. Each of the hinge members 3 is provided at opposite endsthereofwith a plate which; is adapted to. belsecured to the corresponding side plate 1,v aslshown by Fig. 1. The inner ends of' the plates 4% arehingedly con} nected by a pintle or pivot ,boltl5 to one end of astra'pb the said straps'6 being rigidly:

applied to the corresponding top plate 2. The opposite ends of the strapsfi are pivotally connected at thetop 10f the fender by a pintle orpivot bolt 7, thesaidbolt carrying a coil spring 8 each of the ends of which engages and rests uponpne of the strapsfi.

With this construction ;it willy-be obvious" that I each of the plates .1 and *2 may. move about the pintles or bolts 5 and 7 independentlyof the other plates, and that the spring- 1 normally tends to force the top plates 2 to; I .igetherffi Owing to.- the fact that these plates are connected tonthe plates 1, it will. be seen that if the said'plates '1: are prevented from moving spring ii-will tend'rto raise 5 position'so as to form an inverted 'V-shaped canopy or top for the fender, as shown by F g. The fender may thus be dragged over the plants with the side plates 1 disposed upon opposite sides thereof, the

spring 8 holding the top plates 2 clear of the top of the plants so as to do no damage thereto. This hinged connection of the plates 1 and Zalso allowsthe same to be collapsed upon each other, so that the fender will occupy a minimum amount of space when removed from'the cultivator.

The fender is adapted to be secured to the cultivator or plow by any desired means, although in the present instance one particularly desirable method is shown. A pair of bars 10 project upwardly and forwardly from the forward ends of the side plates 1, one end of the said bars being rigidly secured to the said plates 1 by bolts'll, while the opposite ends are provided with opentings 12 adapted to receive bolts or other suitable means for securing them to the beams of a cultivator or plow,not's'hown. If desired these bars 10 may be constructed of one piece, although a desirableconstrue tion is to form the bars of two yieldably and relatively slidable sections 10 and 10 as'shown. The section 10' has one end thereof rigidly connected to the corresponding side plat l'by' means of the bolts 11, the opposite end thereof having adjustably and detachably applied thereto a guide member 13. This guide member'has a channel formation comprising, a base 13 and end flanges '13". The base 13*" has provided therein a pair of similarly formed'openings 13, the said openings being a little larger than the cross section of the bars 10 and 10". Oneof'the openings is adapted to receive the free end of the bar 10, the said bar being secured therei by means of a set screw 14: carried by'the guide 13 and screwed into a snug engagement with the bar 10. The other opening is adapted to slidably receive the intermediate portion of bar 101. One end of this bar 10 is provided with openings 12 adapted to receive bolts to secure the same to the cultivator, while the opposite en'd of the said bar carries a guide I5 of exactly'the same construction as the guide 13', the said guide being provided with openings similar to the slots 13 of the guide 13, one of which receives the free end of the bar 10 which is rigidly secured therein""by 'a set screw 16, while the other opening slidably engages the in 'terinediate portionof the bar-"10 'These guides 13 and 15 are arranged upon the bars 'ro and" 10 with their flang'es'facing each other'fahda spring 17 surrounds the two barsnot touch the ground, thus bars 10 and 10 may have a relative longitudinal sliding movement, the spring 17 serving to yieldably resist this movement, and the spring allowing the fender to fall into the hollows or ride over the lumps with a resilient movement, thereby relieving both the fender and cultivator from sudden or sharp strains. Furthermore, the slidable and adjustable arrangement of the guides 13 and'15 allowsthe'fender to be adjusted longitudinally of the cultivator as may be desirable to cause it to coeperate'm'ost effectively with the shares of the cultivator. Should it be desired to use the fender so that the lower edges of theside plates 1 would allowing the earth to pass. beneath them, the guides may be adjusted and the bars 10 wardly upon the bars 10 to the desired-position. T I

In normal operation the fender, is arranged to be dragged along theground between the two series of cultivator shares. or hoes, which are arranged upon opposite sides of the row of plants tobe cultivated, with the side plates 1 disposed between the corresponding cultivator shares'and the row of the plants and upon oppositesides of the plants, the top plates 2 being arranged over' the tops of the plants, as shown by Fig. 3. The earth loosened by the shares of the cultivator is forced against theisides and top of the fender, and, as the fender passes along is distributed behind it about'the roots of the plants, the earth sliding from the sides and top of the fender. The plant is prevented from being knocked over by the side plates 1 and the topplates 2 prevent the earth from burying the same, The hinged arrangement of the plates of the fender allows one side thereof to rise and fall with the corresponding cultivator beam to which it is fastened as caused by irregularities in the ground without affecting-the other side of the fender, and the yielding and sliding arrangement of the bars 10 allows the whole tender to ride easily and smoothly over the earth without sudden or sharp strains upon either the fender orthe cultivator. 1

Having thus described the invention, what I claim as new and desire to secure by -Letters Patent, is zpushed forhingedly connected to one of the side plates, the said top plates being adapted to be arranged over the top of the plant.

3. A device of the character described including a pair of side plates adapted to be arranged upon opposite sides of a plant, a top or canopy hingedly connected to both of the side plates, and yielding means for normally holding the top in an elevated position over the plant.

4:. A device of the character described including a pair of side plates adapted to be arranged upon opposite sides of a plant, and a pair of top plates adapted to be arranged over the top gether,

of the plant and connected to arranged upon opposite sides of a plant, a 20 pair of top plates hingedly connected toand each of which is hingedly connected to one of the side means for holding the top plates in an elevated position over the top of the plant.
